5 Extending the Layer 2 VPN Technology Pack

You can extend the L2 VPN Technology Pack to meet the business needs of your organization. This chapter describes the content included in the technology pack to facilitate extension.

See UIM Concepts, UIM Developer's Guide and the Oracle Communications Design Studio online Help for general information about how you extend specifications, characteristics, and rulesets.

Important:

To ensure that your extensions are upgradeable and supportable, you must follow the guidelines and policies described in UIM Concepts.

Extending Validation and Auto-Assignment Capabilities

The L2 VPN Technology Pack includes a number of stub rulesets that you can use to introduce new validation and auto-assignment capabilities.

Stub rulesets are blank by default. You can develop your own rulesets in separate cartridges and give them the same name as the stub. After you deploy the technology pack into Oracle Communications Unified Inventory Management (UIM), you deploy the cartridges with your custom rulesets, which replace the stub versions. See UIM Concepts and UIM Developer's Guide for more information.

These are the stub rulesets included in the technology pack:

Extending Configuration Specifications with Stub Configuration Items

Stub configuration items have no content associated with them by default. You use them to add characteristics or specification options to configurations. You can associate characteristics or specification options to these stubs from separate cartridges, so you do not need to unseal a technology pack cartridge to extend it. See UIM Concepts and the Design Studio online Help for more information.

Extending Pipe Terminations

You can add a new Pseudo Wire configuration stub item to model label switched paths (LSPs) within a pseudo wire. To achieve this, you can add a new Pseudo Wire Configuration item with two pipes in it and relate it to the Pseudo Wire specification.

Extending the Layer 2 VPN Termination Model

The Layer 2 Termination specifications include two types of stub configuration items. Table 5-1 lists and describes these types.

Table 5-1 Stub Configuration Items for the Layer 2 Termination specifications

Stub Item Use

L2 QoS

Used to support quality of service (QoS) standards in a virtual leased line (VLL) or VPLS; for example, you can include characteristics such as cost of service (CoS) to determine the priority of incoming frames in a VLL or VPLS during scheduling and congestion handling.

VPLS Control

Used to support additional parameters for remapping VPLS and VLL Customer VLANs


Extending VLL Terminations

You can add a new VLL Termination configuration stub item to use a different Layer 2 technology for your VLL service. For example, you may choose to use ATM as your Layer 2 technology. To support ATM, you may add a new VLL Termination specification for ATM and relate it to the VLL Termination specification.

Extending the VPLS Network Model

The Network Configuration specification includes one stub configuration item. Table 5-2 lists and describes the configuration item.

Stub Item Use

Additional Characteristics

Used to extend BGP- and LDP-based VPLS networks based on the additional parameters provided


Extending VPLS Non Switching Terminations

The Attachment Circuit configuration specification under the VPLS Non Switching Termination Configuration specifications includes a stub configuration item. Table 5-3 lists and describes the stub item.

Table 5-3 Stub Configuration Items for the Attachment Circuit configuration specification under the VPLS Non Switching Termination Configuration specifications

Stub Item Use

Pseudo Wire

Used to extend a pseudo wire by providing a different entity specification for a pseudo wire


Extending the VPLS VSI Model

The VPLS VSI Configuration specification includes one stub configuration item. Table 5-4 lists and describes the configuration item.

Stub Item Use

Additional Characteristics

Used to extend the functionality of a VSI by providing additional parameters for VSI configuration in a VPLS network.
